Transom Service Kit for Mercruiser R, MR Alpha One 1974-1990.

The 1973 and earlier units used a U-Joint bellow without a ridge on the inside which fits into a groove to help sealing.

The 1973 and earlier units also used a gimbal bearing with a plastic race rather than the aluminum race you see on this gimbal bearing.

If you are unsure if you have an Alpha 1 or an Alpha 1 Generation 2, the Gen 2 U-joint bellow is held in by an internal sleeve on one side and a regular clamp on the other.

DO NOT order this kit for models with a plastic race gimbal bearing.

Replaces: Mercruiser # 30-803097T1; Sierra # 18-2601-1; Mallory # 9-72902

Kit contains Outdrive Gasket Set, Gimbal Bearing, U-Joint Bellows, Exhaust Bellows, Shift Cable Bellows, Water Intake Hoses, and Hose Clamps
